Question: Renal Length


 vze3qdxk - Tue Mar 02, 2004 5:37 pm

What is considered to be "significant" when it comes to renal length? I understand that it's not unsual for the sizes of the kidneys to be different, however at what point does it become a point of concern? Also, what causes kidney lengths to change?

Thank you.

User avatar On the contrary, they usually have a slightly different length.
RIGHT KIDNEY-adult length 9.4cm max: 12.1cm
LEFT KIDNEY – adult length 9.95cm max: 12.25cm

Increase in length can be caused by many things such as tumors or hydronephrosis.

User avatar Dear vze3qdxk,

Usually, a difference of 1 cm or more especially if one of the kidneys is getting smaller (atrophic) warrants a work up for the reason why this kidney is getting atrophic.

Thank you very much for using our website https://doctorslounge.com and i hope that this information helped.

Yasser Mokhtar, M.D.
